[QUOTE="keep_hope_alive, post: 7470646, member: 576029"] i keep the MX or BBE off and try to run the HU volume to 30-35. Alpine has clean output at max volume when you keep the sound processing off. sound processing like MX and BBE sounds good at low volumes, as you've found. but i prefer better signal to noise ratio and less distortion. you want your system to have good linearity. that means the sound (bass, mid, treble) are balanced throughout the volume range. I tune using IASCA test CD's, JM Labs demo CD's, Autosound 2000, and a selection of well recorded CD's i've listened to many times. I never tune from compressed music or new "equal loudness - limited" music. New music lacks dynamics so you won't get the desired low end punch. you have to go back to the 80's to find really well recorded music. in the 90's music started to be changed for the benefit of radio playback, and in the 2000's it was changed again for the benefit of portable music player playback. certainly, there are some studios that maintain proper dynamics, finding them is a challenge. get yourself some good test CD's. turn off BBE. lower sub amp gain and lower speaker amp gains. when you start to reach volume 30 you'll have a strong signal going back to the sub amp, so your amp gains need to be lower. adjust your speaker amp gains to balance with the sub. listen at vol 10, 20, 25, and 30 - you want linearity.
